WILLIAM B. ALLEN, OF GOLDENGA'IE, ILLINOIS.

LAND-MARKER.

Application filed July 22, 1912.

To all whom it may concern:

Be it known that I, WILLIAM R. ALLEN, a citizen of the United States,residing at Goldengate, in the county of Wayne and State of Illinois,have invented certain new and useful Improvements in Land-Markers, ofwhich the following is a specification, reference being had to theaccompanying drawings.

The present invention relates to new and useful improvements in landmarkers, which are adapted to be applied to a corn planter, and theprimary object of the present invention is to provide a mechanism bywhich the land marker may be raised or lowered from the drivers seat ofthe planter at will.

A further object of the present invention is to provide a device of thischaracter to be simple in construct-ion, strong, durable and eflicientwhen in use, and be comparatively cheap in the cost of manufacture.

Other objects will be apparent hereinafter as the description continues.

IVith these and other objects in View, this invention consists of noveldetails of construction, combination, formation and arrangement of partsas will be hereinafter more fully described, claimed and particularlypointed out in the accompanying drawings, in which- Figure l is a sideelevation of a portion of a corn planter having one of the ground wallsremoved and illustrating my invention as applied thereto, and Fig. 2 isa rear elevation of the same having my invention as applied theretoshown in full lines in the raised position and in dotted lines in thelowered position.

Reference now being had to the accompanying drawings wherein I haveillustrated corresponding parts by like numerals throughout the severalviews, for a better illustration of my invention, I have shown a portionof an ordinary corn planter comprising a frame A having mounted thereonthe usual drivers seat B and having applied thereto an axle O, uponwhich is mounted the ground wheels D for supporting the frame in theusual and well known manner.

Secured to the rear end of the main frame A of the corn planter adjacentthe middle portion thereof, I have pivotally mounted at- 1, an arm 2having rotatably mounted in its free extremity a disk 3 for marking theadjacent row in the usual manner.

Providing means for raising and lowering Specification of LettersPatent. Patented June 17, 1913.

Serial No. 710,998.

this marker, I have journaled upon the main frame A of the corn planter,an L-shaped lever comprising one arm 4 which extends transversely of theframe and is journaled within suitable bearings 5 which are permanentlysecured to the main frame of the corn planter and depending therefrom. Acrank lever, indicated by the numeral 6, extends longitudinally of themain frame and is journaled within a pair of bearings 7, permanentlymounted upon the said frame. One end of this lever 6 is connected to anextension 8 mounted upon the middle portion of the transverse arm 4 ofthe lever by means of a link 9, whereas the opposite end of this cranklever is slidably connected to the shaft 2 of the marker. The longer armof the crank shaft 6 is bifurcated, as at 10, and each of thebifurcations is provided with concave rollers 11 which extend laterallyfrom the lever. The shaft 2 of the marker is adapted to operate betweenthe rollers 11 so that when the crank shaft is operated, the marker 3will be raised and lowered as desired.

One arm of the lever, as indicated by the numeral 12, is provided with ahandle by which the operator may raise and lower the marker. This handleof the lever extends upwardly adjacent the seat mounted upon the cornplanter upon the right side of the frame thereof. A segmental rack 13 ispermanently mounted upon the main frame A of the corn planter, and aspring actuated pawl 14 is mounted upon the lever arm 12 for engagingsaid rack so that when the marker is raised or lowered, it will be heldin that position.

It will be seen from the foregoing description, taken with a cornplanter provided with mechanism as before described for raising andlowering the marker which will hold the same at any desired angle orkeep it in constant contact with the ground and also provides means forraising the marker when turning from one row to another.

Having thus described the invention, what is claimed is 1. In a landmarking device of the character described, the combination of a cornplanter frame, an arm pivotally mounted at one end upon the rear portionof the said frame, a marking element mounted on the opposite end of saidarm, a crank lever mounted upon the said frame and extendinglongitudinally thereof, one arm of said crank lever being bifurcated,concave rollers mounted within said bifurcated portion and connected tothe arm of the marker, an L- shaped lever, one arm thereof extendingtransversely of the said frame and ournaled therein, an extension formedupon said last mentioned arm, a link connecting'said extension with onearm of the crank lever, an operating arm extending from said L- shapedarm, a rack mounted upon the said frame, and a spring actuated pawlmounted upon the operating arm of the L-shaped lever for engagement withsaid rack, substantially as and for the purpose described.

2. In combination with a planter frame, of a marker comprising an armpivotally secured at one end to the said frame, a marking device carriedby the opposite end of said arm, a crank lever extending longitudinallyof the frame and journaled thereupon, laterally disposed rollersextending from one end of said crank lever and partly encircling themedial portion of the said marker arm, and means for operating theopposite end of said crank lever whereby the said marker may be raisedand lowered, substantially as described.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
